摘要
The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting lossless data packet based on QoS framework in wireless communication system, the method comprising: transmitting one or more PDCP SDUs via a first DRB to a receiver; determining whether each of the one or more PDCP SDUs is successfully transmitted or not on the first DRB, when a DRB mapped to a QoS flow is changed from the first DRB to a second DRB; re-transmitting one or more first PDCP SDUs via the first DRB to the receiver; and transmitting one or more second PDCP SDUs via the second DRB to the receiver.
